I already have had my car protuned. 04wrx with vf34 running cobb AP. I'm using the factory boost controller with gm solenoid on my car. One thing I'm not overly fond of is boost response. I know with the vf34 it could be faster than what I've got. Its not slow but I'm confident it could be faster. I also know I don't have any leaks anywhere. Could I get a manual boost controller and hook it up just like you've got it and have it work out or am I going to run into problems? I also have an ewg is that makes a difference.
